How to connect the CPU-1461 to other PC/104 & PC/104-Plus devices:

the stack assembly

The ISA and PCI Bus connectors of the CPU-1461 are located on the bottom side of the module only, and

are designed to allow the connection on the top position of the stack formed by other PC/104 and/or PC/104-

Plus devices.

We recommend you to follow the procedure below ensuring that stacking of the modules does not damage

connectors or electronics parts.

Always use appropriate antistatic precautions when handling boards

1. Turn off all power to the PC/104 computer and its peripheral devices.

2. Select and install standoffs to properly position the module on the PC/104 stack.

3. Remove the module from its antistatic bag.

4. Check that keying pins in the bus connector are properly positioned.

5. Check the stacking order; make sure an XT bus card are not placed between two AT bus cards as

this will interrupt the AT bus signals.

6. Hold the module by its edges and orient it so that the bus connector pins line up with the matching

connector on the stack.

7. Using even pressure press the module onto the PC/104 stack.

14 PC/104-Plus – CPU-1461 Module

Figure 3 shows a module stack with the CPU-1461 on the top of two PC/104-Plus modules.

If standard PC/104 modules are used in the stack, they must be the lowest modules because they will

normally not include the PCI bus. An adapter module must be used.

CPU-1461

Carrier Module

Figure 3. The Module Stack

Do not force the module onto the stack! Wiggling the module or applying too much pressure

may damage it. If the module does not readily press into place, remove it, check for bent pins

or out-of-place keying pins, and try again.

J4 for Multifunction and VGA

This connector enables the connection of a speaker, keyboard, mouse, battery and VGA monitor to the CPU-

1461.

 System reset

The connection of the multifunction connector pin 9 to ground performs a hardware reset of the

module. It is possible to use an external push-button (normally open) to manually reset the system.

The reset signal is “de-bounced” on the board.

 External Battery

Pin 7 of the multifunction connector allows the connection of an external backup battery.

If you connect a battery, then the voltage must be between 3.0V and 3.9V.

This battery is used when the system is powered down to preserve the Real Time Clock data.

The typical battery consumption with the module off is 7uA.

 Speaker

A transistor that supplies 0.1W to an external speaker controls these outputs. A transistor amplifier

buffers the speaker signal. Use a small general-purpose 2” or 3” permanent magnet speaker with an

8

Ω voice coil. The audio output is based on two signals: one come from the output of Timer 2, and

the other come from I/O port 61h compliant with the AT Standard.

connectors, a speaker, battery and a reset pushbutton.

J5 IDE Connector

The CPU-1461 module provides an interface for up to two Integrated Device Electronics (IDE) hard disk

drives on connector J5.

J5

IDE/DOM

Figure 6. J5 Connector layout

To install the hard disk, perform the following operations:

¾ Hardware installation. Connect the hard disk to the module using a data cable, and then connect the

hard disk to the power supply according to the device’s specifications. Make sure that pin 1 of connector

J5 and pin 1 of the drive or drives are correctly connected. Pin 1 of the interface cable is usually

indicated by a stripe along the edge of the cable. If two hard disks need to be connected, they must be

configured for common operation (i.e. master/slave or cable select connection).

¾ IDE BIOS Setup. The hard disk parameters can be configured using the Setup program. If the hard disk

is connected to the module without setup configuration or with a wrong setup configuration, a time-out of

a few minutes occurs.

¾ Software initialization for specific operating systems. Refer to the OS documentation.

If the soft power management is enabled, a low signal in this pin turns the system on or off.

Note. The VSB (Volt Stand-By) voltage is useful for Power management applications only.

Note. The +12VDC and -5VDC voltages are neither used nor generated by the CPU-1461 module:

they are only conveyed on the PC/104-Plus bus (connector J1) and can be used by other

devices or modules that are stacked onto the CPU module.

WARNING! IMPROPER CONNECTION OF THE POWER SUPPLY WILL RESULT IN SERIOUS

DAMAGE TO THE MODULE.
